Hi I live in asquith, nxt to hornsby, there is a lovely catholic church and school and they have tuesday playgroup within the sch grounds. 10 am to 12 noon. But if you want to travel just a wee bit further a fantastic playgroup in Gordon which runs on a Thursday,10 to 12, in the anglican church hall, a donation and all toys etc and food provided so you only have to assist in putting the toys away. A lovely group of mums who are really good people. I find playgroup australia the organisation an expensive option because you have to pay annual and term fees and provide food. Good luck.
