Our History

History of the Australian High Pressure Water Jetting Association

In late 1991 five water blasting companies and one water blasting equipment supplier came together to form an association. The aim was to provide standards and training to the water blasting industry thus ensuring a safer industry.
The initial companies that formed the association were Allied Plant Services, Barry Brothers, Gardner Perrot Middlemass Vactec and Woma Australia. The initial meeting was held at the Sydney Hilton Airport hotel adjacent to Sydney Airport and there were around 20 in attendance.

The association was based in Wollongong. A company called DMW was selected and David Williams was the first Executive Officer.
Grants were sought from Department of Employment, Education, Training and Youth Affairs (DEETYA) and Federation of Industrial, Manufacturing and Engineering Employees (FIMEE). The grants were used to conduct skills and task audit Australia wide. The two persons involved in the audit were Adrian Hart and David Williams. Water jetting operators from all over Australia were questioned and a report was then developed. This report was then sent to Australian National Training Authority. The report also assisted in the development of standards of training.

The association put together a high pressure water blasting course. The course had a duration of five days was run by trainers from Gardner Perrot and Middlemass. The course was designed for supervisory staff and operators alike with theory and practical components with a formal assessment at the course completion. Courses were run at the Caltex Kurnell and Shell Rosehill refineries.
 At this time the Association in 1995 was being run out of Western Australia and a decision was made to wind up the Australian High Pressure Water Jetting Association incorporated in NSW and reincorporate the body in WA as Ausjet. This was achieved in 1996.

Ausjet continued to grow in WA and was re-launched in 2002 across Australia and quickly gained momentum. In 2006 Ausjet ran a successful two day conference in Perth WA for over one hundred members and associated attendees. The conference was a mix of tutorials, demonstrations and networking sessions as well as supplier booths where new and current high pressure water jetting equipment were on show. Ausjet established a member s website and through that website developed an online incident reporting system. This also led to Safety Alerts being distributed to the members across Australia, New Zealand and beyond. It also enabled Ausjet to collect and analyse incident data for the high pressure water jetting industry.


In line with the Ausjet vision the association set about developing a suite of Nationally Accredited courses starting with the:
The Hydroblasting Induction (HI) a one day water jetting course was accredited and rolled out in 1996.

This was followed in 1997 by an Intermediate Water Jetting Course, later renamed the Hydroblasting Supervisors (HS) Course, this was a two day course.

The Industrial Services Induction (ISI) Course was developed in 2005/6 and lunched in 2007.

The ISI course was a two day course and incorporated a vacuum loading module.

Ausjet also developed guidance notes for Class A pressure cleaning units as well as producing a training video.

In 2013 Ausjet in association with IFAP produced the new Nationally Accredited training Packages for the High Pressure Water Jetting Assistant (1 day) and High Pressure Water Jetting Operator (2 day) skill sets.

The new courses were developed in accordance with the Manufacturing Skills Australia MSA 07 MSASS00002 & MSASS00003 skill sets which form part of the Certificate III in Surface Preparation.

The new courses now supersede the Hydroblasting Induction (HI), Hydroblasting Supervisors (HS) and Industrial Services Induction (ISI).


Ausjet was instrumental in developing the interim Australian Standard AS 4233 (Interim) that was available in 1994. Developing this Standard brought together a team of persons from the water jetting industry with the common goal of a safer industry. This group met on a regular basis working on both the interim and permanent water jetting standards.

In 1999 two joint Australian, New Zealand High Pressure Water jetting standards AS/NZS 4233 1&2 were then made available. Ausjet in 2008 began an internal review of the two joint Australian, New Zealand High Pressure Water Jetting standards. In January 2012 Ausjet made an application to Standards Australia officially requesting a formal review.

SF-043 Committee was re-formed in August 2012 with the aim of revising AS/NZS 4233 1&2 by 2013. Again Ausjet members formed part of that committee.

Ausjet was instrumental in developing with WorkSafe WA an industry Code of Practice for the Safe Use and Application of High Pressure Water Jetting Equipment which was released in 2001.

Ausjet in 2011 worked with Work Safe WA Australia on the revision to the WA code of practice for high pressure water jetting work.
This led to Safe Work Australia asking Ausjet to assist with a National Guide for Managing Risks from High Pressure Water Jetting.
