This template shows an incredible amount of bias in the sections of this table and what ought to be in them. I can list with the Denominations section although there are likely a few missing - surely a link to the Category:Christian_denominations_in_Australia would be better. However, the Churches section ought just be a link to a WP category such as 'Christian Church'. Again there are also numerous Interdenominational Organisations why not just create a WP category? Basically if a group or organisation is notable enough to have a page you will find them in a relevant WP category.
The whole section on politics is just open to bias. Every political party in Australia has Christians involved. No political party is (publically) sponsorted by any church or agency. Having the word Christian in the label doesn't necessarily make it so. Ditch it.
