Alma Park is IN Brisbane (is it not?), with the right attractions, casual membership programme, etc people may in fact choose to visit for say an hour after work, on their lunch break or for shorter weekend visits instead of the drive to Aus Zoo, all bringing in concessions, possibly souvenirs sales etc...
Alma Park is on the North side of Brisbane in the suburbs. It is in fact closer to the Australia Zoo than many residents of the south side of Brisbane are to it. If I was living in the southern or Western suburbs (which I do) and was goinf to travel to a zoo I would continue on to Beerwah. It is also about half an hour out of the city centre so most people aren't going to travel to it for lunch.
You seem a bit defeatist about this zoo, is it a bit of an eyesore..?
Sorry if I am defeatist but I have visited it many times, it is expensive for what you get, there are never many visitors regardless of the day or time and has some terrible exhibits. (The monkeys are awful)
There is no reason a city cannot have a smaller inner city zoo and a larger one on the outskirts... See San Diego, Melbourne, Chicago, New York etc
It is on the outer suburbs not inner city
Sorry is that directed at me..? Did I miss something..?
