Firstly, sorry for going ahead and moving without discussion. I should have forseen disagreement about this and brought it up on the relevant talk pages first, so I think Derek's revert was entirely reasonable.  says I made the move without any explanation, however I did leave the following as my edit summary when making the move: "aussie perth is primary topic - many times the population of Perth in Scotland (even though that is the original), also cf. Wellington, Christchurch, Boston etc." The move seemed logical to me as the Australian Perth has a population of 1,433,217 according to the article, and the Scottish Perth has only 45,000. The Australian one is about 32 times more populous. Wellington in New Zealand appears to have only about seven times the population of its biggest rival, but gets primary topic status. Christchurch in New Zealand is bigger than Christchurch in Dorset by a similar factor, and also gets primary topic status. I'm sure there are more examples. I hope this goes some way to explaining why I made the move. Since two residents of the Australian Perth have now come forward to oppose its move to primary topic status, and because of the historical significance of the original Perth, I'm inclined to withdraw my own support. Sorry for the unilateral action. —
