The citation of Davies v Tenby Borough Council [1974] 2 Lloyds Reports 469 informs you that this case is reported in Lloyd's Reports.

This series contains reports of shipping, insurance and commercial cases, predominantly from England, but also from other jurisdictions such as Canada and Australia.

Accordingly, there is not sufficient information in the citation to know whether this particular case would be binding or persuasive on a New South Wales court. The report itself would need to be examined.
