Weather is pretty good for that time of year. In case you haven't been told, Arapiles is almost all trad (plus bouldering), Grampians is a mix of trad, sport and bouldering, and the Blue Mountains is mostly sport.
If you need partners, camping at Arapiles is a good option. There's usual people there at every time of year, with Easter being the peak. Only a couple of hundred meters walk from the campsite to the nearest climb.
Grampians is a bit more spread out. Northern Grampians is probably a good place to start looking at, and includes Taipan wall as well a lot of the bouldering that international climbers visit for - http://www.climb.org.au/index.php?page_id=10&action=subregion®ion_id=9
For the Blue Mountains, the crags around Blackheath are a good starting point. Easy to access by public transport, and Shipley Upper would be one of the most popular crags in the mountains if you want a partner. http://www.climb.org.au/index.php?page_id=10&action=subregion®ion_id=3 |
