Be thankful you had a 2-hour-old forecast. There's hundreds of airfields out here that don't even get a forecast, yet alone a decent TAF. But to answer your question, so far as I'm aware, there's nothing available to us down here like you can get in the US. No uplinked NEXRAD, no FIS-B'd METAR's, down here there's zero, zip, nada!
About your only possible option would be some kind of SATCOM/Iridium data subscription to access the latest BOM winds-aloft charts, but even then, they can be upto 3 hours old.
