Hi I hope someone can help me. I hold a 189 skilled visa but haven’t yet moved to Australia due to meeting my girlfriend while I was doing my visa application (the law of the sod) I have been to Australia since I got it to kick it into life but need to go before September 2019 and stay there for 2 years to get it renewed. My girlfriend is not ready to move there yet due to her elderly parents but we wouldn’t rule it out in the future so my question is this: Having let one visa lapse would this have any impact on a second application or does it not matter? Many thanks in advance, Rich
