oh and one other i take it that safale is a type off yeast?
Yeah sorry mate, should have been more specific, but it was just a cut n paste job!
To be exact it was Safale S-05 which is an American Ale style yeast.
About the brew, you have a large amount of fermentables in there so it could well take a while to ferment out, however at those temps it would normally be done buy now - try to keep the temp down if possible to a better 18-20deg, but in the NT thats going to mean pretty much a dedicated fridge.
I have had some normal brews sometimes take 3-4 weeks to ferment out fully, when the SG is constant over a few days then bottle, don't worry about the reading the instructions said to bottle at as you modified the recipe by the sounds of it, the rule here is bottle when the SG remains constant over a couple of days.
Just curious also why the boil? Kit's don't really need boils, unless you are doing extracts and hopping yourself for bitterness/flavouring.
When I was doing kits I did small boils (usually 15mins or so) but usually only the malt extract and sugars to dissolve it and also when adding grains or hops.
Don't ever boil the actual can unless it is unhopped liquid malt extract as you will drive away the hops that have been used in the kit.
My biggest advice though is try and get lower fermentation temps if possible, keep an eye out for an old spare fridge.
Or an old broken fridge/chest freezer and use frozen bottles of water to keep the temp down - that's what I do.
