The cricket is probably about 3-5cm long. That type of spider is very, very common in Australian gardens and varies a lot in size (presumably as they grow, and not as sub-species). The larger ones would be about the same size as the cricket. The ones in the photo are likely younger. If you go out with a headlamp at night, you will see dozens of these spiders with their eyes shining back at you. When gardening, I encounter them constantly (almost every minute when digging over soil) but they tend to run away or stay clear and are never concerning.
