Some T-Bus drivers do this in Brisbane from DFO. Some of my connections are very tight and them leaving ~3 minutes means I would have to wait 20 minutes for next one.
I've only used this method a few times and twice they have left early. Once we pulled in on the connecting bus and as we parked the one to the airport pulled out. I found out it had left 3 minutes early. The connections are tight but that, presumably, is to avoid hanging around. If it all ran on time then it would make the trip a very smooth one.
A lot of the times the bus I am arriving on from Toombul has worked out I am going to airport and stops parallel at the first bus stop where the T-Bus is parked and drops me off then goes the 100 metres or so to the designated bus stop.
As opusman indicates, you should be fine but be prepared to miss it. If you have the time and if, as you wrote, you would have a 28 minute wait on an earlier bus then I think I'd take the risk as they are timetabled for every 30 minutes anyway. You might want to check that wait time with the earlier bus as I think you might find that it's 18 minutes and not 28.
, I might take the risk - I can afford to miss the bus and still make the plane reasonably comfortably.
True, but the difference is that there are plenty of other options that are much cheaper and don't involve changing transport. Skybus is a bit like the Sydney Airport train, Brisbane train and the Arlanda Express train (etc), the quickest, most convenient but most expensive option.
. We have to do the same thing next year for our trip to Sweden. Still, I'm happy to pay it for the speed and convenience.
Ah, but Skybus doesn't run at 200km/h
