The Easter long weekend is the favourite last get away before the winter. Being a four day weekend means there is enough time to get away to the shack, the farm or wherever. The roads on Thursday out of town can be busy, similarly coming back on Monday.
Do your shopping before Thursday, but the shops will be open on Saturday.
EVERYTHING IS CLOSED ON GOOD FRIDAY. ESPECIALLY THE PUBS AND BOTTLE SHOPS. Some small supermarkets and petrol stations will be open.
Easter monday is like a normal public holiday and the usual places will be open.
