This well decorated entrance is to Al-Zahra mosque in my suburb. It's a Shi'ite mosque, with adherents mainly from Lebanon, but also many Iraqis (and others I guess). It was established in 1980, certainly the first Shi'ite mosque in Sydney (and it may still be the only Shi'ite one; not sure on that).
Unlike when I lived in Turkey, however, you never hear the call to prayer.
It's also rare to hear church bells in Sydney , something I remember fondly from living in England. Noise laws I think.
