Just back from a trip across inland North
  Queensland (north west of Townsville, south west of Cairns, about one-third of
  the way to Mount Isa). We took the Herveys Range Developmental Road from
  Townsville (now sealed except for 41 kms) to the Gregory Developmental Road
  (sealed but narrow in places, look out for road trains!!!!), staying
  overnight at Greenvale (immortalised by Slim Dusty in the 'Pub with
  no Beer' song), then on to the Lynd Junction - the junction of the Gregory and
  Kennedy Developmental Roads).
