loads of opportunity for uncrowded waves....probably right under your eyes as well in locations you would least expect it......I have even surfed them on the Goldie (thanks to asea and Chrispy)........
Midweek winter and outside school holidays will get you them most of the time.....the short days stop a lot of the early crew from getting out for a wave and the after work crew can not get there....a cold wind normally stops a few others as well. Cold water locations are definitely yr friend if you hate crowds.
There are lots of places that are relatively uncrowded most of the time as well...for obvious reasons I will not name my fav ones here

but once you get out of the heavily populated centres crowds drop big time. Places with lots of options are also good locations to scout. You need to put the time in to find what you are seeking but the rewards are well worth it. I surfed with 4 others blokes this morning for an hour in some of the most perfect waves I have ever seen. A few of my mates reckon I went to the wrong place - they also scored uncrowded perfection and were only a 15 mins drive away

Once you get the hang of what spots work in what conditions you will soon realise when its time to down tools and head there. I have fav spots that I will drive 2.5hrs for just to get a good session in - because its worth it. My justification is that 10 day trips a year like that and if I get 5 or 6 of them right its worth it - way cheaper than a trip to the Ments!!!!
