@Karen Hodge, I hear you!! Sometimes I think the estate agent should carry quite a bit of the blame actually. If they do their job correctly like you see in the adds on TV, they should bring these discrepancies to the attention of the sellers, stand on their morals and say if you can't get it better than this, then you'll have to find someone else to sell your home!! I know you can't make everybody "house proud" but the saying "do unto others" springs to mind. I bet if these same people bought a house not up to scratch, "a current affair" would hear about it but they don't think it wrong to simply walk out on a house that isn't being left nicely for the next family!! I have some friends that recently sold a house in Essendon, Melb and whilst the buyers were back and forth selling their own home, my friends kept watering the plants and even did things like painted out the wardrobes because of the scuff marks made over time!! They cleaned the entire two storey house from top to bottom and finished by mopping the floors as they were exiting. The buyers were so taken by the entire home, they bought it with almost all the furniture that my friends had in it!!

PET PEEVE: INDOOR BAREFOOTERS NEWSFLASH: It is a plainly observable though controversial fact, to me at least, that very few people keep their indoor floors pristine enough for barefoot traffic. However, that does not seem to stop the oh-so-carefree, INDOOR BAREFOOTERS from taking their grubby, 'floor-feet' on little excursions upon coffee tables, chairs, couches and beds, etc. YUCK! Imagine seating yourself upon someone's couch and making the mistake of placing your hand beside you ON the couch, or forward upon the coffee table, only to feel an icky graininess...or stickiness? So, then you're stuck with continuous hand-washing throughout your visit because THEY could not be bothered to keep their 'floor-feet' off anything....their home being their slovenly castle and all. The YUCK factor and the politics which invariably follow my well-meaning interventions, (I'm an idealist), makes me an irritable, reluctant guest. Which ironically, never seems to stave off the invitations (sigh)! But, it also makes me a tyrannical host: "feet off my settee, Jerri! Not on my mid-century coffee table! No! Your white socks are no longer white, Jade! Aaargh!" WORSE YET, these oblivious INDOOR BAREFOOTERS tend to then touch and scratch their grubby 'floor-feet' while chatting, and touching their faces, fixing a meal or eating something...OR, shaking my hand. Oh, the humani-...'hygienity!' I feel ill!!! Yes, yes, I know that I'm whining AND yes, I know that there are worse things in the world: children suffering in Africa etc., but now that you mention it, even THEY tend to wash their feet BEFORE placing them on furniture! Maybe because they value the little they have. I know this from firsthand experience!! SIMPLE SOLUTION: Indoor shoes! Outdoor Shoes! And, when you place your feet upon anything slip OFF your shoes to reveal your lovely clean feet, which will appreciate the pristine lack of graininess from your last considerate visit. Anklet and pedicure but...floor-feet!!

Australia has nice examples of painted and rendered Art Deco homes. If it was a different kind of brick I would say keep it, but I think painting/rendering would really brighten the place. I love the windows. Although all pics here don't exactly match your style, they are all of that era. As mentioned in above comments, there are mix of landscaping styles that suit from conifer/gravel/grass to cottage rose garden to an Australian native garden. Do what reflects you and how much time you have for your garden.

Are you sure the roof is stainless steel?? That is VERY expensive and only used in very exposed corrosive coastal locations since it lasts forever. I think it might be Zincalume, a low cost but very durable and very common roofing material that has a light silvery surface and should last for 50 years. Definitely do NOT paint the roof black (or any dark colour), it would add more than 10° to the internal heat load, and you would have to spend so much more on insulation and on-going AC costs just to get back to where you are now. Have the roof checked and repaired by a roof plumber instead. If it's an old leaky galvanised iron roof at the end of it's days, replace it with zincalume. The porch roof looks like it needs replacing, but I would replace it with new roofing, possibly the insulated sandwich panel kind, that has a smooth white underside, then add a gutter to the front edge so you don't make your visitors walk under a waterfall in the rain. The canvas awning suggested earlier would not last as long without looking tired and would require the removal of existing roof structure, so I think it would be the more costly option (and you would still have the waterfall problem). I would leave the front fence as is, it ties in nicely with the house, but trim the tree. The back deck could easily be roofed to match the front, and be more useful to tenants with weather protection. It would be good to make all trim colours the same, and against the cream brick I think the dark grey you have on the front door and columns works quite well. I would make the other windows and trim, as well as the weatherboards over the back door match that if it just involves painting. However, it's not essential and if it means changing powdercoat finishes it would be too costly to be worthwhile in a rental.
