Wave Rock: Although it's really cool to see a big rock in the shape of a wave i'm not sure if it's worth an almost 400 KM busride (one way). If you happen to be around there you defenately should take a look, but we had a guided tour of just half an hour.
To make the long trip justable they also brought us to Hippo's Yawn, a big stone that looks like a yawning hippo, and Mulka's cave, a small cave with a few aboriginal paintings which are hard to see in the dark. I found out what i've been staring at when i was back home and looked at the pictures taken with a flash light. For more pictures see my wave rock travelogue
I have to preface this by saying i've never been on one before but, going on anecdotal evidence, avoid the Pinnacles tour. 'the Pinnacles' are basically several groups of limestone jutting out from the sands in the beach north of Lancelin. Apparently it's breath-taking at night but most tours are run during the day.
Go to the Pinnacles and go to Monkey Mia ! But take your time : spend one week on such a trip, not 2 days with a organized tour where you will spend 12 hours on the bus, and 1 hour in the pinnacles and 2 in Monkey Mia. Respect the magic, take your time, stay 2 days in Monkey Mia you will remember those days all your life!
Money changers. They're not very easy to find in perth. The bank I went to will NOT exchange 100.00 US Dollar bills unless you have an account with them. You also will NOT get the rate advertised on business TV such as CNBC. Thomas Cook will exchange money for you with no problems but the rate is rather low. Oh, don't forget that they charge you a fee (5.00 to 7.00)for every exchange!
Watch out for the cheap car rental ads. They are advertised everywhere and you can't miss them when you arrive atthe airport. However, those cheap places charge you for picking up the car at the airport. This charge can be mor ethan the daily rate! It may be cheaper to go with one of the big companies that has a place at the airport.
It is very hard to buy Australian Made souvenirs that are at a reasonable price. Perth is full of souvenir shops but I would say that less than 3/4's of their stock is actually made in Australia. So remember to check the labels if you are after a genuine Aussie made product.
At the Barrack Square there is this Bell Tower. It looks quite nice but nothing special. Avoid to get in. It´s a waste of time (and money).
Esperance is one of my favourite beaches in Western Australia, the water is so clear, the drive towards the beach is stunning.
BURSWOOD CASINO is a good place for gambling, but becareful...don't stay there too long, even if you are winning..., you can even lose at the end. Don't want to go home with empty pocket do you???
