Embezzlement: Lingering embezzlement issue

Hi I'm an Australian now living in the US (WA) as a Legal Resident, I know there are jurisdictional issues with the info I'm requesting but it's all loosely common law right? Anyway, there was an office investigation in '97 into misappropriation/embezzlement of funds, I was interviewed, statements were taken, I wasn't working during some of the known 'loss' periods. Nothing more eventuated. I left Australia in mid '98 married an American and now am living happily ever after, kids the whole deal. I contact my folks and tell them we'll be visiting Australia in the summer and my dad says 'oh by the way you might have an issue, your mom signed for some papers in '99 and there was a summons to appear in court, you may have a lingering bench warrant for failure to appear'. Could this be true? Would they flag my passport for a bench warrant? I obviously don't want to be arrested at the airport almost 10 years later with my husband and kids, would a statute of limitations apply? Is a summons considered commencement of proceedings? Any suggestions appreciated, I ideally do not want to open a can of worms if it's not an issue but there is some lingering anxiety.
