Have you tried the search Pro function here on Houzz?

Yes but just comes up pros not in my area

I’m assuming that you’ve just not made a connection with the designers you found in your google search of your local area? Being able to communicate is so important and I’d concentrate on finding that person rather than narrowing in too much on a particular style. It’s rare for regional designers to specialise, but truly a good designer should be multi faceted. One of the advantages of all the tech available to us (and the lessons from COVID) is that on site meetings can be reduced which may make engaging someone outside your area less cost prohibitive, once you do find the person with whom you’re a good fit and who’s a good fit for you. Best of luck

You could try going on fiver. Somewhat safer than having a random come into your home at the moment. Fiver can give you a idea before you touch base with an actual designer. Take clear photo's of what it is you want decorated, upload to whoever you pick on the site and pay them $5 or whatever there fee is. Obviously you want to check out there profile first. Send them what you want making sure you explain in detail so you don't pay for something you don't want. Ask for a timeframe and wait. That is just one way to go if you don't find someone in your area.

Most designers can do all styles but obviously have their own specialties. You can always ring any designer to discuss over the phone / video call (some charge) and get a feel for them, they are and can be just as picky about the clients they take on and if they don't think you and them are a good fit they maybe able to recommend an industry professional.

Good Luck with your hunt.

I’ve had a look through the designers I follow on Pinterest/Instagram which is another great way to find someone that will suit your style. Have a look at:
Deb from andyanddeb via Instagram
Donna Guyler Design
Cedar & Suede
Alanna Smit Interiors
Tara Dennis
Melinda Hartwright
All the above on Pinterest. Not all are NSW but work across areas.

If you're after more decorating rather than design look at Kate Walker from Victoria. She has an offshoot KWD which will ship flat-lay ideas around Australia. The website is also really helpfulin finding your style.
