Redline, it's been quite a while since I was a member of Hartwell MCC. I'm sure they would have no issues with you turning up to a meeting to phorograph proceedings. In my day there was always one or two photogs with semi serious gear taking shots. I expect you should be able to sell some images at the meeting. I purchased a pair of prints from a fellow who snapped me overtaking a bike at Phillip Island.
Broadford Park is just 4 min. north of the township of Broadford on the Hume Hwy, about one hour north of Melb. There is a bitumen road racing circuit there and a big motocross track. The road circuit is very tight and up and down so you can shoot flat across the straight, up into some corners or down onto a heap of places. You can shoot from very close to the edge of the track in some spots. They race all sorts of bikes from 125cc up to the superbikes (1,000cc) and sidecars. Plenty of overtaking etc.
I got this year's dates from this newsletter :-

If you've never been to Phillip Island, make the time to go, It's
the most magnificent place to race, view and photograph.
Cheers,
