Adelaide's Priority Engineering Services collapses, 120 jobs impacted ADELAIDE high-tech firm Priority Engineering Services has collapsed, impacting 120 jobs. The Elizabeth-based engineering services firm, which started in 1984, had received a number of Federal and State Government grants to extend its machinery expertise from automotive to defence, mining, aerospace and other areas. In the past it has been a supplier to defence giant BAE and automotive manufacturers Holden, Mitsubishi and Ford. It is understood the SA government provided a $200,000 grant last year to try and help them through their difficulties. Owner Peter Paige is hopeful the company's Elizabeth site will be sold soon, which may help revive the business.
