Management changes that have removed the CFI and rumours that they have a disspensation from CASA for pilots to do more than 900hrs a year...
Not hard to get, most GA companies I have operated under had a part 5 exemption allowing 1000 hours per year. Catch was they were limited to 90 hours a month.
Most scenic operators in the Kimberley don't take the exemption as they need the 100 hours a month in the dry and don't get close to the 900 hours a year with the quite times in the build.
