Prior to "Z-day" I'll be living in a Mexican style hacienda, four rectangular walls high windows and a courtyard with thick wooden gate to outside world. Greenhouse on the second floor, solar panels and a wind power water from air generator (basically wind spins turbine, powers refrig panels and creates water from condersation). Large underground water tanks for rainwater and aforementioned generated water.
This is on the outside of a large town (40,000 residents) perhaps a twenty minute drive.
Some sort of hybrid car that uses electric (perhaps rechargeable hydrogen cells) and regular fuel. Along with bicycles etc.
Guns, ammo, food and medical supplies stockpiled. Protective clothing like motor-bike gear, skate pads, helmets with clear visors and wet suits for underneath regular clothing. Melee weapons like crowbars, machetes and hatchets that serve several purposes.
"Z day" occurs, gather family, wife+kids if I have them, plus siblings and parents if nearby. Call previously warned/selected friends. If they can get themselves plus family to my house or nearby they've got a spot in the house.
These friends include a vet and two former (at that point in time) soldiers, one of whom is an excellent mechanic and the other has a portable bullet press and knows how to remake bullets.
Hide for a couple weeks, start raiding nearby properties (being vary careful), salvaging stuff and gathering livestock (we'd already have some chickens, a cow or two). Rescue survivors if safe to do so.
If the zombies are there for the long haul, plant crops in the soil during the day, under the watchful eye of armed sentries. Hunt Kangaroos. Fence off livestock if there's too many to keep in the courtyard. Protecting them would be important but not life risk worthy. Reinforce already high windows and sturdy gate. Razor wire furthermost fences and gates around the farm.
Slaughter and burn any zombies that approach. Only allow appropriately inspected survivors in and only if they can carry their own weight.
If the town greatly depopulates of zombies, say if they hypothetically move to a larger urban centre, raid the town itself.
Eventually start taking the fight to them, setting up traps and murderous shooting galleries on buildings on the outskirts (where we can recover all our casings).
Once zombie numbers have drastically decreased or they die out completely rebuild society ever vigilantly. Planned breeding to reduce consanguinity (aka incest/inbreeding). Teach the kids.
If survivors want to gather around my fort, they're welcome as long as the agree to the feudal semi-communistic nature of the place, with me as their Hetman.
Edit: That said unless the origin was in Australia, it would be hard to spread it here. Worst case scenario our defence force shoots down any plan or ship that approachs our borders. If they actually infect a city, we have large areas of openness to fight them on and spoil if we have to (napalm etc).
