You will first need to look at providing some protection to the prevailing winds and plan some dense planting for buffering. You will need to give and idea on budget. That is a massive area. It will also depend on region. Talk to you local council and nurseries

Tubestock will be your friend. I would plant ground cover drifts of Birthday Candles banksia, grevillea and callistemon. The Gardening with Angus site can help with plant selection. You can stabilise the slope cheaply with chicken wire laid over it. This means you could also plant a quicker growing Happy Wanderer to fill in gaps. You have lots of space so some lovely flowering Waratahs and Callistemon trees would be impressive.

For your other garden beds, Lomandra looks great against Corten. And Acacia Limelight And Casaurina Cousin It are also sculptural and look good.

Hi , agree with bigreader on stabilising the slope, there are some great products on the market for your site , geocell is worth researching, tube stock planting will save you heaps and they grow faster, lots of grasses and ground covers will look fabulous and stabilise the hill.

gorgeous location ..consider wide grassed ramps to criss cross the slope diagonally from top to bottom, 1.5m+ plus wide paths will allow for easy mowing and two people to walk side by side...Tube stock is so much better for big areas needing multiple plants and you'll get better results quicker than the more expensive bigger plants ...use mass plantings of the same species like Correas and Westringeas... we had great success stabilizing slopes with a variety of Casuarinas suitable for the local area and fast growing wattles were good to create quick windbreaks while other trees and shrubs became established..(the wattles are short lived and gaps left when they go are filled in by other maturing plants) buying multiple tube stock we were able to economise with deals that included the plants, labour for planting and tree guards for orders of hundreds ..digging trenches (as apposed to single holes) and planting closer together, adding drip irrigation, mulching heavily and using tree guards for shelter and to prevent drying out and/or fences to keep out kangaroos will also help... keep the areas close to the house free of shrubs and garden beds and include wide mown paths as snakes are usually happier to stay in the rockeries and shrubs, don't feed pets outside to attract mice and snakes and, given a suitable area, a dam is always a bonus to create a destination for walking around the garden and giving wildlife their own space and, as a welcome surprise, we found that bulbs and irises introduced some colour in Spring and Autumn and propagation from a few parents plants quickly expanded into mass plantings..happy gardeniing

Sounds gorgeous oklouise, love the idea of having a destination could be a simple path or a bbt bolder one using sleepers, how fabulous is th location.

Australian Plants Online have three types of Lomandra on special for the Easter Weekend at $1.95/tube for an order of 20. They are usually about $4. So if you’re ready to plant have a look. I’ve no affiliation with them just received their newsletter.

Thank you all so much for all your advice, I absoluteiy love all your plant selections, can see them looking beautiful in our setting and really enhancing the beautiful view.

My worry is with higher growth inviting snakes, we have already met a few! I know they will be there anyway but would like to keep them away from the house. I understand it's important to stabalise the slope and these plant would be ideal but given the snake problem are we better to use some of our existing large rocks scatered, not grouped, with low ground covers running in-between?

Oklouise and Julie Herbet - we have an existing large natural spring fed dam in a gully below the slope where many wildlife gather, hidden in natural growth, we had similar ideas but this is a future plan we look forward to visiting.

having lived in a similar situation with resident snakes for many years we found that as long as we had no garden beds next to the house, kept clear wide walking paths and mown playing areas for humans and wide garden beds with overgrown rockeries where snakes could hide unmolested we had no conflict with snakes and, if you and especially children, always wear long pants, sox, covered shoes and leather gardening gloves there should be no extra risk from snakes..(it could be worthwhile to ask a snake catcher for specific advice to be better educated about the local snake breeds and any special risks) we were told that Australian snakes have short fangs that cannot pierce most clothing and they don't want to be around people and some hiding places for them will keep everyone safer... my small children were taught to march around the paddocks stamping their feet and we never saw any snakes close to the house ..surprisingly we also discovered that our flock of geese and chickens wandering around seemed to discourage the snakes who only returned when the geese left home

Thanks so much oklouise, being 'city people' moving to the country we know we have LOTS to learn and are very grateful for your great advice.

oklouise: Thanks for the tip re the solar lights, we will definitely do that as we have lots of wildlife of all shapes and sizes who come visiting !!

We haven't moved in yet but one thing we have noticed already is how silent it is, the only noises we hear are cows and sheep in distance....much nicer than traffic noise!

A few friends live in the local area, which has been great, as they have already made connections with some good trades, we are finding it's very hard to get anyone to come to you in the country, especially landscapers.

try and think of delays as an opportunity to give you more time to think and plan (and save)..life in the country is supposed to be slower and quieter..enjoy

I wouldn't worry about snakes and rocks, they will take up residence in your garden regardless. All you are doing is depriving yourself of a nice landscaping feature. We have black snakes, king browns and pythons in our yard, and we're urban.
