Face Masks


The term "face mask" includes cloth masks, plus single-use face masks (commonly called surgical or medical masks), and N95/P2 respirator face masks. All of them, manufactured properly, are suitable for use to prevent the spread of Coronavirus (COVID-19). We strongly recommend you buy Australia Made face masks so as to ensure an effective, quality product.

Fabric or Cloth Face Masks

Fabric or Cloth face masks are any nose and mouth covering made of washable fabric. It's recommended a cloth mask made of three layers of a mix of breathable fabrics to ensure adequate protection. It does not need to be surgical quality to be effective.

You can even Make Your Own Cloth Mask.

Fabric/Cloth Face Mask are reuseable and should be washed after each use. See How to Wash Cloth Face Coverings.

We have available the Australian Made range of Sharkskin Envirus advanced technology fabric, antimicrobial face masks. (See below.)

Surgical or Medical Level 2 and Level 3 Facemasks

Surgical or Medical masks are made with a non-woven melt-blown polypropylene layer and available in various levels of protection. These are single-use, disposable masks only so can't be washed and used again.

Medical or Surgical Face Masks should be manufactured to Level 1, 2 or 3 according to the Australian Standards. Revised in December 2015 the standard AS 4381:2015 for Face Masks are now performance-based on 3 tests:

  • Bacterial Filtration Efficiency (BFE) with Differential Pressure (Delta P) & Synthetic Blood Penetration Resistance. Fluid resistance is measured mm Hg, masks are rated according to performance.
  • L1-80 mm Hg. L2-120 mm Hg. L3-160 mm Hg.
  • Fluid Resistance: The ability of the mask to limit the passage of blood or body fluids from the outer facing through the mask layers to the inner facing.

Level 1. Applications: For general purpose medical procedures, where the wearer is not at risk of blood or body fluid splash or to protect staff and/or the patient from droplet exposure to microorganisms (e.g. patient with upper respiratory tract infection visits General Practitioner).

Level 2. Applications: For use in emergency departments, dentistry, changing dressings on small wounds or healing wounds where minimal blood droplet exposure may possibly occur (e.g. endoscopy procedures).

Level 3. Applications: For all surgical procedures, major trauma first aid or in any area where the health care worker is at risk of blood or body fluid splash (e.g. orthopaedic, cardiovascular procedures).

In general surgical/medical face masks are way more comfortable than the N95 respirator style face masks. However, because these surgical masks are in short supply for medical professionals and emergency service providers, the government is suggesting you use a non-medical fabric face mask.

P2 or N95 Respirator Face Masks

A P2 mask, also known as a P2/N95 mask or P2/N95 respirator, is a disposable face mask that is specially designed to filter the air and block particles above a certain size, including smoke and fine dust. The only difference between P2 and N95 is the region of classification and its testing requirements — P2 is European and N95 is the USA equivalent.

P2 or N95 respirator face masks are not recommended for use in the community and not advised to be used outside of healthcare or specific industries under health advice. We should prioritise the use of N95 respirators for those personnel at the highest risk of contracting or experiencing complications of infection.

The Goorangai shipwreck (aka HMAS Goorangai, MV Goorangai) was an auxiliary minesweeper of the Royal Australian Navy (RAN). She is historically significant as the first Royal Australian Navy surface vessel lost with all hands, Australia's first naval loss of World War II, and the first Royal Australian Navy surface vessel lost in a war.

The entire ship's complement consisting of three officers and twenty-one sailors (twenty-four in total) were killed when the HMAS Goorangai was sunk in an accidental collision with MV Duntroon on 20 November 1940. Only six bodies were recovered, of which five were identified.

Blasting operations in January 1941 reduced the remains of the Goorangai to large and small sections of steel plating which protrude from the sandy seabed. A small cylindrical boiler (2 m x 3 m) is lying on the northern end of the site. Broken machinery and boiler sections are scattered around the site, and occasionally wartime relics can be seen.

What little remains is of little interest to wreck divers, with heavily overgrown wreckage, however, the fish life is generally prolific. The remains cover approximately 200 square metres of the seabed, and a considerable length of hull plating stands proud of the sand to a height of about two metres. The remains of the hull have been colonised by a diverse assemblage of colourful encrusting organisms, such as bryozoans, sponges and soft corals. This, in turn, provides an ideal habitat for both free-swimming and sedentary fauna, including many fish species, cuttlefish, sea horses, nudibranchs and starfish. The abundance and variety of marine life, in association with the shipwreck, makes the HMAS Goorangai a popular destination for sport divers.

The Goorangai lies in the South Channel and is subject to shipping, which also means anchoring is prohibited. Diving on slack water is a must.

Goorangai Shipwreck History — Built in 1919

The Goorangai was built in 1919, as a 'Castle' type steel single screw steamer, of 223 ton gross, based on a North Sea design, at the State Dockyard, in Newcastle, NSW, for the NSW Government. The overall length of the vessel was 117 ft (36 m), with a beam of 22.1 ft (6.74 m) and a draught of 13.8 ft (4.21 m). She was driven by a triple expansion steam engine of 68 horsepower.

The Goorangai was sold to Cam and Sons in 1926 and refitted as a fishing trawler.

At the start of World War II, the Goorangai was one of thirty-five privately owned vessels requisitioned by the Royal Australian Navy as auxiliary minesweepers. She was commissioned on 9 September 1939 as the HMAS Goorangai for service as an auxiliary minesweeper.

Goorangai carried three officers and 21 sailors, all of whom were Reservists. David McGregor, who had been skipper of Goorangai in her trawling days was an exception. He was persuaded to sign on by the RAN as Commanding Officer of HMAS Goorangai with the rank of Commissioned Warrant Officer.

Following the sinking of the SS Cambridge and MV City of Rayville in Bass Strait by German mines on 7 and 8 November 1940 respectively, three minesweepers including the HMAS Goorangai were ordered to the sweep the shipping lanes and approaches to Port Phillip, and within a fortnight were able to locate and destroy forty mines.

HMAS Goorangai Sinking — Collision 20 November 1940

The Goorangai had anchored off Queenscliff on the evening of 20 November 1940, however, a freshening southerly wind made the anchorage more exposed, so it was decided to move over to Portsea to gain more shelter, under the command of Warrant Officer David McGregor, RANR. As the Goorangai proceded across the South Channel without lights, at 8:37 p.m. on Wednesday 20 November 1940, she was struck forward of the funnel by the outward bound troopship MV Duntroon which was leaving for Sydney loaded with troops. The Goorangai was cut in two and sank in less than a minute in the South Channel, Port Phillip.

Wartime security prevented the Duntroon from heaving to or switching on searchlights to look for survivors. However, the Duntroon did lower lifeboats, fire rockets, and sound three blasts on the whistle to alert the residents of Queenscliff. When the lifeboat Queenscliffe reached the scene of the disaster the crew found the minesweeper sunk in about 15 metres of water with only the tops of the masts visible. Despite an extensive search for the HMAS Goorangai crew of 24, only six bodies were recovered.

The minesweeper HMAS Goorangai has the tragic distinction of being all at once Australia's first naval loss of World War II, the first Royal Australian Navy surface vessel lost in a war, and the first Royal Australian Navy surface vessel lost with all hands. The Goorangai is a designated war grave and should be treated with respect.

Because the HMAS Goorangai wreck lies in the main shipping channel and was considered a hazard to navigation, she was demolished with explosives in January 1941. The remains of the wreck are very scattered.

On 16 November 1995, the wreck of Goorangai was declared a historic shipwreck as specified in the Historic Shipwrecks Act (1981).

DISCLAIMER: No claim is made by The Scuba Doctor as to the accuracy of the dive site coordinates listed here. Should anyone decide to use these GPS marks to locate and dive on a site, they do so entirely at their own risk. Always verify against other sources.

The marks come from numerous sources including commercial operators, independent dive clubs, reference works, and active divers. Some are known to be accurate, while others may not be. Some GPS marks may even have come from maps using the AGD66 datum, and thus may need be converted to the WGS84 datum. To distinguish between the possible accuracy of the dive site marks, we've tried to give each mark a source of GPS, Google Earth, or unknown.
