It is not available here as far as I know, but you can get a similar product by following this recipe.
Get a tin or two, depending on how much you want of Condensed milk. Place the cans of condensed milk in a deep saucepan and cover with water, topping up with hot water as necessary. Bring to the boil, then reduce the heat and cover with a lid. Leave to simmer for two hours. Remove from the water and cool completely (very important, make sure they are completely cool before opening.) When you open the cans you will find it has turned to a golden sticky caramel.
It will probably be a little sweeter than Burndst or Ski Queen.
