Hi,
A recent post [http://www.ozbargain.com.au/node/95146] showed that there are cheaper options should you wish to become a zoo member, pay a once-off fee & then receive free entry for a year to most major zoos around Australia.
This will especially save you $$ if you are in Sydney as Taronga's prices are through the roof.
Zoos included = Perth Zoo, Taronga Zoo and Western Plains Zoo, Melbourne Zoo, Werribee Open Range Zoo and Healesville Sanctuary and Adelaide Zoo and Monarto Zoo
Cheapest option for a single adult =
$80 - Perth Zoo (http://www.perthzoo.wa.gov.au/shop/join-zoo-friends-the-bene…)
Cheapest option for a single child (Under 15 years old) =
$41 - Perth Zoo (http://www.perthzoo.wa.gov.au/shop/join-zoo-friends-the-bene…)
Cheapest option for a concession card holder/senior =
$77 - Adelaide Zoo (http://www.zoossa.com.au/getting-involved/membership/members…).
This works out even cheaper if you're 2 concession card holders as the second is only $57.
[Note - Melbourne is cheaper for a concession card holder but you have to pay a $15 application fee]
[Note2 - Taronga's concession is only $79, if you live in NSW then it might be better for the benefits - http://taronga.org.au/membership/become-member/membership-rates/membership-rates]
Cheapest option for 1 adult and 1 or more kids =
$86 (if you're a concession card holder) or $106 (if you're not) - Melbourne Zoo including a $15 once-off joining fee (http://www.zoo.org.au/members)
Cheapest option for 2 adults with no kids =
$140 - Perth Zoo (http://www.perthzoo.wa.gov.au/shop/join-zoo-friends-the-bene…)
Cheapest option for 2 adults with 1 kid =
$181 - Perth Zoo (http://www.perthzoo.wa.gov.au/shop/join-zoo-friends-the-bene…)
Cheapest option for a family of 2 adults and 2 or more kids =
$184 - Melbourne Zoo including a $15 once-off joining fee (http://www.zoo.org.au/members)
So don't pay too much - and say hi to the monkeys who only pay peanuts to be there, just like an ozbargainer!
While this is great, you're potentially screwing yourself over by abusing this loophole.
Australian Zoos are private institutions that get by without (or with minimal) government support.
By purchasing another zoo's membership you're cheating your local zoo of finances to stay open.
Plus by exploiting the loophole, you risk having the handy loophole closed for those times where you might want to visit a zoo on holiday!
