To go with the bizarrely popular LED palm tree, Bunnings have 1200 LED, 60m multi-colour string lights for $35 if you're already thinking ahead to next Christmas. This is twice the usual bulb density for longer string lights, and they also claim to have a memory hold controller meaning that they can be used properly with a timer. The multi-colour variety was the only one that would let me select delivery and was available click-and-collect in a store local to me. Warm white and White are also listed at the same price but there may only be limited in-store stock.
Low voltage and solar Lytworx 250 LED strings in white, warm white, and multi-colour are also down to $7 with varying availability.
