Cant remember how much, but yeah those multi storey parking lots.

The animals i think we headed out of the city a bit (hence why that kangaroo got run over).

Yeah, perth's not a forest kinda place. Desert, yes.

Malay? Thought this was our Msian Chinese MO 

Night temps rarely drops below 10. Unless you're further out from the CBD.
I lived bout 30 mins east of CBD and nights are usually 7-9.

Day times usually 16-18, unless sunny day. Rare in winter.

Get racist by white and asian Australian

Wildlife sightings very depends on your luck. There were kangaroo sightings at Perth airport and inside the carpark on level 2/3 before.

Btw Albany isn't really doable as a daytrip. Its about 4-5 hours drive 1 way, unsure about how long much via Kattaning. I'd suggest going via 1 route and returning via different route. Can see the greenery change 2-4 times depending on the route you take.

Also you may encounter wildlife on the roads during night and especially at dusk/dawn when the roos are most active. Have had a few close encounters myself and know several people who've hit them. So I'd suggest staying overnight for this safety reason as well, especially if you've not been out of Perth city before.

If you're interested and have the time, check out Valley of the Giants at Denmark

Lucky you haven't encountered them. Just be extra vigilant in CBD and nearby surroundings on Friday/Saturday nights. Especially the train station.

Best to research more on driving at night before making your decision. I've encountered heavy fog with ~20m visibility at night but this was driving up north and during autumn. Unsure if winter can create these conditions.

You're right Albany doesn't have much. Denmark is about 45mins west of Albany, not EU's Denmark. If you're going via Katanning , it'd be the red line. Hence why I suggested Denmark for different route (blue line) back to Perth. Time permitting of course.

When I road trip I tend to stop randomly anywhere I feel nice. Depends what interests you otw. I found a random pink lake nearby Denmark before.

Then you'd know how rowdy Northbridge can be at nights. Seen shit like Aboriginals using cross junction as boxing ring there 

Train station is between CBD and Northbridge. The tracks are literally the north border of whole CBD. Yes its almost beside that underground entrance.

Drove in NZ as well and yes fairly similar in OZ depending on route. I think blue line may have more stops than red but I usually stop in the small towns instead of standalone stops (not many iirc)

Busselton has a famous long jetty if you're interested for a detour.

Got money, everyday is great in Australia other than facing subtle racism by the whities there. Its granted, and understandable as its their country being infiltrated by Asians leeching the country's wealth.
