Climbing around melbourne in June-July 2011

I will be in Melbourne for a conference from June 28 through around July 10. I would love to get out and climb at the Grampians, or Mt Arapales or wherever... Bouldering, Sport climbing, or trad climbing would be awesome.

I am wondering what the weather might be like and hoping to meet up with some partners.
I can bring a rope and draws, probably not trad gear.
I am currently a 5.12+ sport climber and a 5.11+/12- gear climber.

Let me know!
