Is it easy to make friends?

My family (me, wife, two young kids) are hopefully moving to Perth soon from the US (job offer dependent) and we’re VERY excited at the opportunity both personally and professionally (can’t wait to get out of the craziness that is the United States). I’m just a bit nervous for such a big move and worried our social lives might take a major hit. Is it pretty easy to meet new friends in Perth? All the posts/blogs/podcasts, etc make me think Perth is absolutely amazing and very friendly. I’m just a nervous dad wanting to make sure I don’t put my family in TOO tough of a situation. Thank you!
