The fact that you are not in control of where you end up means you quickly lose focus of where you are, by the time you've jumped on and off a few buses and trains there is no telling where you'll end up.
Our cheap public transport makes this a really cool option, you can end up in places like Two Rocks, Mundaring, Helena Valley or even Pickering Brook... chances are you'll discover a heap of suburbs you never knew existed and a heap of fun places you never would've found otherwise.
It takes eight and a half hours to walk from Fremantle to Hillarys... I know because I did it. It is a story I will be able to tell over and over again with the same great enthusiasm because it is such an odd achievement in the modern world.
Shoes, thongs, barefoot, it doesn't really matter. Just stand out the front door, look in a direction and go that way. If you see something interesting in the distance go to it. You may end up lost but that just leaves you with the fun of finding your way back again.
Find a new beach Trigg, Sorrento, Cottesloe, Scarborough... don't you get bored of going to the same beaches all the time? Sure they are great beaches, but how do you know you've found your favourite until you've been to every one?
North Beach, hidden between the dog beach and Mettams Pool
If you have a car or bicycle take a ride along West Coast Highway down to Fremantle and beyond or West Coast Drive up to Burns Beach. There are dozens of hidden and little known bays and beaches along our famous coastline just waiting for someone to call them home.
Been to every ocean beach? There are still a tonne of river beaches to discover. From the estuarine beaches of the lower Swan to the fresh water of the Canning and Avon every river beach has its own little peculiarities.
Browse around a supermarket How often do you do the weekly shopping and buy the same products time after time? They're your safety products, the ones you know you like, so it's fair enough that you keep going back to them.
But aren't you curious that there may be something better? If you have a few hours to kill why not head down to the local supermarket and spend some time browsing through the thousands of products you've never even given a passing glimpse?
It can really pay dividends, I recently found my new favourite mass-produced barbeque sauce by doing this. You could even go shop shopping; i.e. looking at some of the other nearby shopping centres (just don't tell your local) to see how their product range and price stacks up.
The great Australian past time is a great wait to kill a few hours at any time of day or night. If you have access to a rod and hooks all you need is a few dollars for bait and a six pack of beer to be set.
It's often been said that fishing is quite therapeutic and relaxing, waking up early and casting a line in the fresh morning air is certainly one of the more peaceful experiences in life. And the evening fish with a mate or two is a great way to unwind after a hard day's work.
Even if you're just starting Perth offers a great range of places to practice and a good variety of species on offer to keep you interested (and well fed). So go on, time to go see why all those crazy people cast their line night after night.
Catch the train to Guildford, walk across the line to the Tourist Bureau to collect a map of walks in the area and discover the rich history in this little town. There are some great coffee places, too.
