オーストラリア法については、州法と連邦法があってよくわかりません。
山田敏之「先進諸国における児童ポルノ規制」（外国の立法）を参照。
送った人も日本法の「本邦から輸出罪」（７条５項）
第７条（児童ポルノ提供等）
4 児童ポルノを不特定若しくは多数の者に提供し、又は公然と陳列した者は、五年以下の懲役若しくは五百万円以下の罰金に処し、又はこれを併科する。電気通信回線を通じて第二条第三項各号のいずれかに掲げる児童の姿態を視覚により認識することができる方法により描写した情報を記録した電磁的記録その他の記録を不特定又は多数の者に提供した者も、同様とする。
5 前項に掲げる行為の目的で、児童ポルノを製造し、所持し、運搬し、本邦に輸入し、又は本邦から輸出した者も、同項と同様とする。同項に掲げる行為の目的で、同項の電磁的記録を保管した者も、同様とする。
6 第四項に掲げる行為の目的で、児童ポルノを外国に輸入し、又は外国から輸出した日本国民も、同項と同様とする。
オーストラリアで捕まった人は、所定の目的があれば７条５項「本邦から輸出罪」の共犯（国外犯）になる可能性がある。
所定の目的があれば６項「外国に輸入罪」も。
オーストラリアから帰国したら、日本警察も待っているので注意してください。
第10条（国民の国外犯）
第四条から第六条まで、第七条第一項から第五項まで並びに第八条第一項及び第三項（同条第一項に係る部分に限る。）の罪は、刑法（明治四十年法律第四十五号）第三条の例に従う。
