I think there may be 2 perspective.
1) If you are a service provider then you wont need to claim back any GST since you are the producer your self such as advertising creative agency, cleaning agency for eg.
2) if you are a trader/ distributor/ selling stuff which are produced by someone, then you need a GST account to claim back the GST which your product supplier sell to you with the GST included unless they are below 500K which I think it a very low chance and you maybe dealing with many suppliers then it will even be slimmer chance unless all also newly setup manufacturers.
