Hi Johnny,
There are only two places I know of that sell Trumpers here in Oz, but if others know of more please jump in and let us all know.
The first one is ...........http://www.artofman.com.au/store.php?idstring=37,12
and they are actually based at Lewisham so that is pretty good for you Johnny.
The second one is at ..........http://www.ludlows.com.au/ludlows/sp...jsp?c_id=10004 based in Melbourne
Just a quick price match between the two I see that the alum bar is vastly cheaper at Ludlows, maybe worth checking out a bit more extensively. I have been buying my stuff from Ludlows, but their range seems to have changed because I cannot see the Coral Skin food anymore, but perhaps they would be worth contacting.
In regard to razors I would be buying from one of our members here as it will have to be honed etc before it is shave ready, this maybe despite what any sales person is trying to tell you that they are shave ready straight out of the box so to speak.
There are lots of vendors here who would be only to happy to help you make a selection. Tony Miller at http://shop.thewellshavedgentleman.com/splashPage.hg jumps immediately to mind because he has great starter kits which include all the essentials for starting out from scratch. IE Razors, hanging strops, paddle strops, brushes etc etc the whole kit and caboodle. And his quality you will not better anywhere, all for a very fair price.
Hopefully this will get you going, but be warned, this is a very addictive thing you are getting into, and life as you know it will never be the same again, and neither will your bank balance. :D
Give us a hoy anytime.
John
