Hi Laurin,
The problem is for anyone to take you climbing they have to drive way south.. Singleton is a long way out from Perth (an hour or so drive) and in the wrong direction unless your going to Pinjarra but its still a long way out of the way to pick you up.. You could have caught the bus to Rockface or Hangout and maybe had more of a chance of hitching up with some climbers there.
Hope you get the chance to go to Peak Charles at Easter, sounds like that will be fun.
