Hmm, no personal experience with the ones you mentioned.
Do you have a drone that needs some repair, or have you used one or both of those and want some feedback form others ?
I just googled
< drone repair Australia > and got this map come up (linked left).
Limited option in Canberra it seems (nil ?), but it might be worth trying one in Darwin (says temp closed).
If you're prepared to ship, then location isn't a problem.
I know UAV Me is up Brisbane way, knows his stuff and have met him up there.
D1 Store does repairs too by the looks.
But sometimes it's cheaper and better value to use DJI even outside of warranty, their prices are usually quite fair, and knowing their gear better than anyone can possibly nail a problem much easier, faster, and therefore less costly.
