I have been lucky enough to go to the four Slams and completed my Career Slam in Australia back in 2018. This post has links to all of my fan guides for visiting the Slams. Hopefully these will be useful for anyone planning a trip in the future. The posts include lots of detail and tips about buying tickets, getting to the venues, what to take/not to take, review of the courts, food and drink, shopping and plenty more! Happy to answer any questions 😊.
