Rear Patio of Apartment at a Birch street Manunda Cairns Queensland,while observing satellites as we often do, my partner and I witnessed what looked like two satellites of a magnitude -4 or brighter travelling along side each-other in a South to North direction at what was a typical Satellite altitude. Only, these two objects blinked on with intensity that caused us both to let out a gasp, and an expletive, as we watched the object/s get brighter as they moved, and had a connecting tube like structure between them that emanated a milky glow, very dull compared to the brightness of the lights. The Object/s travelled side by side as a single unit for up to 20 seconds before blinking out simultaneously, not to be seen again. This observation took place at 18:44 Local Time GMT +10 and left us both in awe. We watch Satellites most evenings, and are familiar with aircraft and other phenomena, but this was a stirring observation that made us search for other possible witnesses on-line, finding None so far.
