Most parts of the world have a semi diurnal tide.which is 1high every 12ish hours.
Perth however has a diurnal tide, which is one high/day. Not sure why, but it is probably some complicated physics thing. Or a conspiracy...
Maybe so you can't tell if a tsunami is coming. Oops sorry forget on BOM the photo/picture/diagram shows we aren't in the tsunami watch area so we couldn't possibly get a tsunami.
I'm pretty sure Perth is relatively safe from earthquake tsunamis due to its location and the shape of the ocean floor.
This little pdf is a bit of a summary of a preso I went to, but can't seem to find the main powerpoint.
