明年放寒假准备让我爱人带着儿子到墨尔本来和我一起团聚过春节。我爱人现在持有的是过桥B签证,允许多次往返,儿子需要申请探亲旅游676签证。因为我在澳洲,到时只有我爱人带着儿子一起从国内飞过来,这种情况的话,是不是需要出示公证书,证明我同意我爱人带儿子过来看我呢?因为676签证申请表上有这么一段话:Children under 18 years of age, travelling alone or without one or both of their parents or legal guardians, require notarised authorisation from the non-accompanying parent(s) or guardian(s) to travel to Australia.
