Where in netball is the wing attack allowed?

Okay, so basic principles: a netball court is divided into thirds. Each team has an attacking or goal third, a defence third (aka the other team's goal third) and both teams share the centre third.

The WA can play anywhere in the centre third, but for the centre pass she must stand just inside the goal third until the whistle blows. She can also play anywhere in the goal third, but NOT inside the goal circle or she'll be called offside. The WA is not allowed anywhere in the defence third (other team's goal third).
