Ooh, this is the geminids for tonight is it? Haven't kept up with it lately. I thinknit depends on what part of Perth you're from.

Its a bit late but you could have a look/call Perth Observatory to see if they're open and doing something, they're still mostly out of the Perth light corona.

Failing that, i'd get out maps, and if you're East of Perth, travel 45 mins further East (Toodyay, or Mundaring Weir, or plant yourself in the middle of the forest like Christmas Tree Wells or something (watch for roo's); If South travel 45 mins South maybe inland due to the light pollution from Mandurah and Rockingham, so Pinjarra, or Waroona dam way (watch out for the roo's); If you're North pick a spot near the beach 45 minutes North from you, at this time of night that freeways gonna get you pretty far North pretty freakin quick, just don't go anywhere you can't get back out of i suppose.

I think the tricknis to get as far away from the light pollution of major centres as possible. If you can get into the Wheatbelt there'd be plenty of spots to pull up out there, but i think that might take more than 45 mins even at this time of night.

What time you thinking of heading out? Best times are usually super late at like 2am or 3am I think.
