Is it possible to display GPS coordinates that span two MGA zones on the same map?

Hi, I have GDA94 GPS coordinates I collected in Queensland in MGA Zone 56, and a few a little further to the west in MGA Zone 55; however, I haven't found a way to display GPS coordinates from both zones correctly on the same map. The GCS of my template shapefile is GDA94, the units are in decimal degrees (no PCS). I've tried adding my GDA94 GPS XY data to my map and batch transforming the template shapefile and GPS coordinate shapefile to projected coordinate system MGA Zone 56. The result is that all GPS points I collected in MGA zone 56 appear where they should do, but Zone 55 coordinates do not, they appear at the correct latitude, but too far to the East. Is it possible to display GPS coordinates that span two MGA zones on the same map? Also, I have checked my GDA94 GPS coordinates against a Queensland Govt Roads dataset and there are no data collection errors. I'd be grateful for any advice here!
