5 years you say... cba 60 month term deposit best rate there is atm. never take risks with money you can't lose, seriously.
I wish the seriously wasn't required but most people do take risks they can't afford.

Your a funny man Boz, but I'm not a financial advisor I'm an econometrician who models financial risk and any advice is personal, not professional.
At your age you do need to be risk averse, as you get older it becomes more difficult to regain loses so you do need to be very careful with your money and work by the bankers creed.. assume nothing trust no one when dealing with your money.
Term deposits do lock up your cash and you will be penalised if your break one though the penalty is just a re-adjustment of the interest, but you need a good reason ie buying a house, medical, that type of thing.
Interest rates will stay low for at least the next 2 years, 5 years is a very long time in forecasting interest rates so difficult to know, especially in this economic climate. I just recently re-invested a term deposit at 4.2 for 7 months which is the best short term rate atm. I choose a 7 month term cause I'm building a new house later this year.
It really comes back to what plans you have for the money; if you just want an income stream from slab of cash you aren't going to use for a while then a long term is okay otherwise you can choose a shorter term and shop around for rates that suit. All the 4 major banks are solid, but you might get a better rate at a small finance shop but with added risk... remember there are no free lunches in finance and if a deal sounds to good to be true then it is.
If a term deposit doesn't suit (they pay interest each 6 months or on maturity) then the next bet is the share market, but you do have to do your homework and devout some head space to understanding the companies you invest in. Revenue stream will vary as some listed companies pay good and bad dividends, but shares a really a long term investment, 10 -15 year cycle of boom and bust so you do have to pick the entry and exit point with care which does take some planning.

lunch time and sry about the long post, but it's never simple.
