Entry to the fair is a gold coin donation, and Surfside Primary School is located at 31-65 John Dory Drive, Ocean Grove (approximately 25 minutes' drive from the Geelong CBD).
A couple of extra tips:
Free parking is available at the front of the school, in neighbouring streets, and at the nearby Shell Road Reserve.
If you need to get some cash out beforehand, Ocean Grove Marketplace Shopping centre is located 850 metres away (about a 2-minute drive or 10-minute walk). There are several ATMs, plus a Woolworths store, where you can get cash out for free without making a purchase.
If you're after some showbags, make sure you make this your first stop, as they tend to sell out very quickly. Showbags are located near the Freddo Quest, in the school garden.
