Australia does indeed rank modestly according to Global RTI Rating (presumably in large part due to the institutional inertia associated with conclusive certificates), just ahead of Canada, another country that uses the principle, and just behind the US. Of course, the model is not Australia's but the UK's, which sits ahead of all three, trailing e.g. South Africa, which also has cabinet confidentiality. Perhaps none of these are a model of best practice, but it might be helpful to explain why rather than simply dismissing an established principle.
(As an aside, I'm finding it difficult to parse the phrase 'Australian court to be a good model to work on', but I assume you mean the Australian executive, which is what FOI/RTI relates to)
