Another one - the cost of public transport and the unlimited free parking at the train stations. If you need to do a journey that goes on any or all buses/trams/trains within a two hour time it only costs you one swipe of your Metrocard (although the price does vary depending on the time of day but my husband's peak-time commute to and from the Seaford station costs $3.80 each way). And the trams/buses are free in the city centre (between the Entertainment Centre and South Terrace (I think)).
If you look at the time my train commute from Seaford to the CBD takes against the cost, it's astonishing value for money, especially when you factor in the extra entertainment value of the Noarlunga crew when they get on-board!
The 1st time I went sea fishing with my son off the Cornwall coast we caught a shark, the captain kept the shark to sell but he cut the jaw out so we could have the teeth, they were not in bone as such but gristle/cartilage, so we boiled it up, boy oh boy did it not only stink the caravan out but the whole damn site, flies which would put the outback to shame too, but hey we got the teeth and proud of it!
