Tenants denied keys by “House Rules”

Greetings all, I’ve joined from NSW, the question I have regards the rights of a Strata Scheme Tenant living with a Owners Corporation and whether the Residential Tenancy Act 2010 is still relevant since the Owners Corporation has told me that it isn’t in my particular case. I have lived as a tenant/strata tenant with my wife for over 5 years now in our building when a few months ago we had 1 of 2 car park key fobs withdrawn because of a new house rule. I tried to explain nicely to the OC that under RTA 2010 Section 70 – 2, that we were entitled to each have a key but they said that this legislation did not apply and that as the Owners Corporation and Strata they were covered legally to withdraw keys as they saw fit. They said that the Strata Agent had told them so and legal counsel had concurred and that was that. Furthermore, more my rental agreement was with my landlord and had nothing to do with them. I spoke with my landlord and agent and they said that since Strata had said no that their was nothing they could do. I have a great relationship with my landlord and agent and are reluctant to take them to tribunal. Any advice would be welcomed since I’m interested to know how I can get my other car park fob back….ohh the strata directive is not a by-law, it is a house rule, Thank you
