There's at least two in Sydney. One near Bondi and one around St Ives. The one around St Ives was a little controversial but the council eventually permitted it.
Although I don't know if the Bondi and/or the St Ives eruvs involve their own physical wires? I thought it was deemed sufficient for the rabbis to just "declare" various sets of third-party power lines / phone lines as constituting the eruv, or am I mistaken?
I'd assume the Bondi one also, because I suspect it's not really valid unless continuous and monitored, per the article. Although I'm no expert.

I live within the St Ives eruv. At least some of the opposition was unquestionably antisemitic — I recall receiving at least one antisemitic screed in our mailbox during the time of the council debate. (That one went something along the lines of ‘the Jews are trying to kick out all the non-Jews’ etc. etc., for two pages of fairly small text.)
