Venue address on the poster is 618 Ballarat Rd, Ardeer 3022. The Sunshine Mosque contact page lists the same address and identifies the mosque as the Cyprus Turkish Islamic Community of Victoria. Surah al-Hadid is Surah 57 of the Quran, and its name means 'Iron' (Wikipedia). No search result mentioned this specific lecture or the speaker Mahmut Temurci, so the speaker's credentials are unverified. The poster does not state a target audience, so none is assigned.
