I will suggest you to contact a construction company. They can guide you properly. I have done mistake of starting home renovation without getting the proper information of SOP’s in lockdown and I got a fine of 600$. So do not start any renovation before having proper knowledge of lockdown rules. There is a company named fast labor hire, they helped me a lot in my home renovation and they also guide me about the all rules. You can also contact them and if you want to hire laborers for the renovation then I think its the best recruitment agency in Sydney.
