Hi @ivanptr
This has turned into an essay! Oops!
I'd be inclined to phone the helpline on dulux.com.au or the on British Paints one. They also offer excellent advice on colours! There are SO many shades of white! But do beware! Everybody you encounter will want to make good sales figures and there are alot of products out there that you really don't need! So research lots of 'how to paint' articles and videos. You won't need paintbrush cleaning products! Cold water and soap do that very well! And ask people what their experiences of painting are!
The walls look like they have a raw finish so you'll need to apply undercoat first though. As the walls are new, just a good dust ought to be enough to clean them - or use the vacuum cleaner. All of the paint will need to be specifcally for bathrooms though, as it needs to contain a mould inhibitor. Dulux Wash & Wear Plus is available at Bunnings - a 10L can will give you 2 coats.

You'll need to cover the floors and surfaces. I used masking or packaging tape. Overlay the edges of flattened cardboard boxes a bit, and securely tape down. They provide a secure surface to walk over and they stay in place! And it's better for the environment! You will also need to make sure all the nails and other fasteners (eg staples) have been well hammered in and there are no bumps. If the heads are showing, get a nail punch and hammer them into the board by about 3mm. I got a set of 5, and the extra 1mm & 5mm have come in handy!

When it comes to hammers, pay a bit more and get a good one! Research them. You want to look at hammers with a heavy head. I've got an Estwing and am very happy with the quality and ease of use. Ive heard some tradies pay $800 for their hammers! It's important to get one for the long term!
Once you've driven in the nails, fill the holes with putty filler. When dry, lightly sand to a smooth finish.
For the brushes, you'll only need to do the trim and edges by hand. I've recently used Oldfields Pro series brushes. The 'Ceilings, Walls & Door' brush has the paint going on very smoothly and gives an excellent finish. And the 'Windows, Cornices & Architraves' is a great little sash cutter in smooth and even application. When buying brushes, I'd avoid the cheaper ones, as you often find the bristles come out when youre painting (very annoying!) and often the finish is so bad it needs to be redone.
You'll need a good paint roller and paint tray (wide). Don't load too much paint on the roller or it will spatter. Do some research on the roller covers, as I have a very old pure wool one, and I've been unable to find them anywhere! Before putting paint into the tray, put it a plastic bag with opening at the flat end where you hold it. Try to mold it into the shape of the tray so it will catch the paint. Then on the underside and at the top, tape it so that it won't move around too much. Practice by putting water in the tray first! You want the water to be taking up the space of the tray bottom and corners, and not forming a puddle in the centre of the tray basin. When you're finished for the day, just pull off the bag and dispose of it. Saves alot of clean-up time and paint going into the waterways. Always follow the pre-use instructions for the roller cover! When you pour paint out of the can, always put the lid back on. If you get interrupted or take a painting break, put the wet roller and/or paintbrush in a plastic bag or roll in a wet cloth. This will avoid them drying out.
When you're painting, the biggest 'helpers' you can have is both a wet cotton cloth and a medium sized paint scraper! When there is an oopsie in your paint border (say onto the cabinet) then wipe it off as soon as you see it! The cloth over a sharp edge (fingernail or scraper edge) will give you a nice sharp edge. But don't worry too much about the drips! A light touch with the scraper will whip them off glass and benchtops very easily. If paint dribbles dry out before you see them, just lightly sand, wipe off dust with damp cloth, dry, reapply paint and blend the edges. All paint colour dries to a sightly lighter colour. So don't worry when it looks different. Check it the following day.
The first step is to paint around the border of the wall with the brush. Try to get sharp edges.
Then the do the walls with the roller.
Then do the trim - usually just architrave, door frame and maybe window. For the door I use the roller. The inside edge is a brush job though (avoid the hinges and screws). Many people do the walls in a matt finish and trims in a semi-gloss or gloss finish.
The Bunnings expert in all things painting is @EricL . Now that I've tagged him I'm certain he will offer you many more tips and tricks! But don't get anxious about doing it - when it comes to 'oopsies' white paint is very forgiving!
Good luck!
