Justice Paul Cronin was satisfied that Mr Nhan was aware of the order, despite not attending, as the former sportsman sent two text messages to his 'gold-digging' wife the day after legal papers were emailed.
The messages take aim at Ms Okien for being driven by fame and money.
'I chose to ignore several people who warned me of the true reason you were with me,' the message reads.
'What I love about this process is that it has finally exposed the real 'wife' and the true reason why you pretended to love me all these years; for a bit of fame and money.
'Happy birthday to my sl*t, wh**e, gold-digging wife! Hope you enjoy your present! Love your ruthless husband!'
Mr Nhan also said 'all the best finding a guy who will give you $343,262'.
The sportsman had previously listed his assets to the court as far less than he owned and transferred the money to a 'Ms C', claiming he owed her $500,000.
While the court ordered Ms C to return the money to a trust, to be held until settlement, the money had not turned up nearly five months later.
Justice Cronin accepted the couple's assets were in excess of half a million dollars.
As a result, Justice Cronin ordered Mr Nhan to pay his wife the money she sought, as well as her $19,309 legal costs.
However, the court also noted Ms Okien would likely not receive any money from her husband as he demonstrated blatant breaches of court authority.
