Western Arthur, South Coast and Southern Ranges planning

Hey guys,
I'm heading down to Tassie to do Western Arthurs traverse and South coast. I'm just wondering how is it with mosquitos down there? Should i bring a repellent and mesh along? Has anybody done Southern ranges track? I was just wondering how is the wading through New River Lagoon? Is it better to go bare feet or get wet the hiking boots? Was anybody buying fuel in Melaleuca? Is it usual gas bottle available in there? Is it reception in Cockle creek or Lune river for Optus or should I buy Telstra SIM card?
Thank you for helping me out with my planning.
