Anywhere with wind...
The reality is that in the depth of winter we get a lot of wind out of the west which does kill most spots. If the wind is from the NW, North Kirra is usually the go for a wave session. There can be the odd Southerly that comes though as well which usually means the southern end of the Gold Coast or Neil St on the Sunshine Coast.
