Description:
From sea-stained dispatches to data sent back from deep space, Southern Signals is the story of Australia’s use of communications to bridge vast distances through war and peace, exploration and growth.
Communications have been vital at every stage of Australia’s history. From the time the First Fleet transport ship Prince of Wales limped back into port eight months after leaving Sydney Cove, to the breakneck rush during the 1970 Apollo 13 crisis to bring Parkes’ famous radio telescope on line, this book shows how adoption (or not) of emerging communication technologies has influenced key events, and formed the. backbone of Australia’s development as a society and relationship with the world.
Chapter topics include: dispatching mail to Britain from a convict colony, and then around a big country; the arrival of telegraph, telephone, and television; wireless radio and Antarctic exploration; wireless radio entering Australian homes; the coming of airmail; Australia’s role in televising the moon landing; communications in search and rescue, Australian newspapers; the internet and the opportunities and risks of the future.

Puppy tested & approved
Color: 12 Tennis Ball
I ordered these squeaky tennis balls for my cocker spaniel. She absolutely loves these tennis balls with the squeakers in them! She plays with them all day, and chews on them frequently. We have not had any problems with her, breaking the tennis balls, which is generally the issue we have with her. The tennis ball fuzz stays on the ball very well, which is usually an issue with standard tennis balls, because my dog likes to peel off the yellow fuzz on all tennis balls. She has not been able to do that with these. I will definitely be buying these again , but will not need to anytime soon as these are extremely well built.

Bright color and tough skin both great
Color: Regular-Orange, Size: 2.5"(Medium)-12 Pack
These tennis-style balls are, as promised, much tougher and thicker-skinned than an ordinary tennis ball, being made as a fetching ball for dogs. I bought them as foot covers for the legs of walkers used by the elderly, a very popular use. They work extremely well to protect rugs and flooring, and to make a quiet gliding cover, easier for seniors to move smoothly without snags. The usual tennis balls used for this purpose wear out pretty quickly, but this ball was made to be repeatedly fetched and gnawed on by your Rottweiler, so it's a big improvement. You will need a good cutting tool to score in the crosswise slits where you insert the walker leg; it's too tough for your household scissors, but that's just the point, right? It's tough.
Very much recommended!

Not great quality
Color: Regular-Red, Size: 2.5"(Medium)-12 Pack
My dog is 7 months old, about 35lbs as of this review. These balls barely lasted a month as they all kept breaking if thrown against anything or just bounced repetitively. The color is good so that you can see it better in the dark, but I would not say these balls are worth the price.
Update 2023-12: After posting my review the seller contacted me and provided me with two free sets of balls as an apology for the bad quality of the original set. So far these are holding much better with my dog and she loves to play fetch with them.
