The ignorance on Getbig is deafening. Educate yourself here about photographer's rights.

I suggest you take your own advice.
"SUMMARY OFFENCES ACT 1988 - SECT 21G
21G Filming for indecent purposes
(1) Any person who films, or attempts to film, another person to provide sexual arousal or sexual gratification, whether for himself or herself or for a third person, where the other person:
(a) is in a state of undress, or is engaged in a private act, in circumstances in which a reasonable person would reasonably expect to be afforded privacy, and
(b) does not consent to being filmed,
is guilty of an offence.
Maximum penalty: 100 penalty units or imprisonment for 2 years, or both.
(2) For the purposes of this section:
(a) a person "films another person" if the person causes one or more images (whether still or moving) of another person to be recorded or transmitted for the purpose of enabling himself or herself, or a third person, to observe those images (whether while the other person is being filmed or later), and
(b) a person is "engaged in a private act" if the person is engaged in using the toilet, showering or bathing, carrying on a sexual act of a kind not ordinarily done in public or any other like activity."
Posting the photos here with the text you supplied would indicate that you are a pervert who gets his kicks from taking photographs of women and children and in breach of the law. Is that why you deleted them?
Please don't hide behind the "It was a public beach" argument. It's intrusive and when it's done for sexual gratification downright sick.
I wouldn't bother calling the DEA, save the money and call a doctor, you need help.
