Brian , good to see you are still on the go, safe travels.
Hammo "it is what it is" Has its good points, you don't have to go into Airlie, on line shopping from Coles, use the resort facilities,good coffee these days, some nice resturants, local airport, good for guests in and out,and Marina staff very willing to assist both in and out of your berth.
Fuel used to be cheaper than Airlie but it is the high season.
I even used to haul Tidahapah out there when I was berthed at Laguna Quays.
Mackay Marina berths have different lease lengths so this may explain the disparity in prices.
I am happy with my $700.00/month for B8 that I have now. It may even be the berth you were in.
Anyhow safe travels.
