SEO First Page. Website issues all fixed up to render well with Google

My website coffsplumber.com.au it not showing up on Google even after 1 year from being uploaded. Ranks on pages 40-50 for some terms. It's a simple site. Only 3-4 pages. I need any Google console issues sorted and any reasons for blockages removed and my site to be showing on the first page for: plumbers in coffs harbour, coffs harbour plumber, plumbing business in Coffs harbour, coffs plumbers, drainage coffs harbour, drainer coffs harbour etc. Any keywords like these as well.
Note: Errors fixed, Google console issues fixed, must show on first page of google.
