dave.jpg Kais Contractors was founded in 2004 when Directors Dave Kais and Sharon Kais purchased their first grader.  Dave Kais had worked in the Civil and Mining industries since he was 17 years old and learnt every aspect of earthmoving on all mobile plant equipment.  During this period, Dave has worked his way from mobile plant operator to Earthworks Superintendant with some of the largest and renowned Civil and Mining Contractors in WA. 

Dave Kais prides himself with his vast knowledge and experience he can give his business and clientele to meet their project needs.

With Dave's expertise and array of contacts in the industry, fellow Director and founder Sharon Kais paved the way to make Kais Contractors a successful Plant Equipment Hire business with an impressive record!  Prior to establishing Kais Contractors, Sharon has had over 26 years of expertise in accounting, finance, payroll and contracts for major companies such as Woodside, O'Donnell           Griffin, Australbricks, Micropay and Temples WA. Sharon is a member of Women in Mining (WIMWA) and is currently helping CCFWA to promote Women in Civil (WIC) for their members after winning the award "Women in Civil 2012". This was such a great honour and very rewarding after all the hard work establishing the  company to where it is today.


Sharon Kais has also been nominated for The Entrepreneur of the Year Award 2014. The awards program recognizes entrepreneurs who demonstrate excellence and extraordinary success in such areas as innovation, financial performance and personal commitment to their businesses and communities.
