RAAus PC + nav endo averages out here, (CTAF in regional WA), @ 45-50 hrs TT @ $220/hr = $11,000
Conversion to GA RPL is straight forward then and usually 2-3 hrs in C172 doing mostly IF work, plus 'test,' plus Class 2 medical + other paperwork such as Engrish speaking test. Cost .. say 3 x 350 + couple 100 for medical = $1300
Going via the RPC to RPL route probably saves you a couple thousand, but you are then capable in both categories. Should you wish to instruct later in career - being both sides capable is going to be important as flying schools are becoming RAAus + GA under the one roof.
We've not had any problems with conversions - but that's not surprising because our instructors are high time Grade 1's with RAAus CFI quals. You don't teach people any differently just because the aircraft has numbers or letters on it. The competencies required are the same, and that's where the 'recognition' under Part 61 originates.
Just one old instructors viewpoint. happy days,
