Sportingbet Deposit $30 get $150 offer ending

I'll leave this one in the forums as its a bit of a grey area as it's gambling related.
The best bookie promo in Australia is about to finish. Sportingbet's deposit $30 and get a $150 free bet.
On Monday they are changing to a matched first deposit offer which majority of the bookies are now on. Much less than the current promo.
Here is more info about it

As long as gamble responsibly this is a massive bargain in my books.
