I can't answer your question but James Dunn wrote this for nabtrade in May 2018 - it appears a rise in the A$ against the US$ is a negative for GNC (but also important are trading margins and how various crop prices move, I'd guess):

Any fall in the A$ against the US$ would also benefit companies with significant percentages of their revenue coming from the US, such as Boral, Treasury Wine Estates, Macquarie Group, CSR, BlueScope Steel, Austal, Cochlear, Flight Centre, SDI, Carsales.com.au, Aristocrat Leisure, Ainsworth Gaming Technology, Hansen Technology, News Corporation, Twenty-First Century Fox, Seek, Sims Metal Management, Orora, IPH, Mayne Pharma, Sonic Healthcare, GrainCorp, Integrated Research, SomnoMed, Ansell, Breville, Adelaide Brighton, GWA, SDI, Navitas, Bega Cheese, Incitec Pivot, Ardent Leisure, Altium, Transurban, Nufarm and Orica.

The caveat is, however, that all that matters in the long run is a healthy business, with growing market share and increasing earnings over time. It does not do these companies’ shareholders much good if there are issues with the underlying business, at the same time as they are theoretically benefiting from a lower A$
