Families are loving this…

  • Emma, mum of a 10 and 6 year old

    My 10 year old was a very reluctant reader and was also not interested in school at all. We thought we would give the Mind Expanders Club a go, as he used to be so curious in the world, and I am so excited. He loves reading the letters, the light has gone on in his eyes again and he is asking questions again. My 6 year old is also enjoying it, we go through it together. I would highly recommend this to any family who wants to help their kids love learning. It’s also just so fun, we love the characters.

  • Nicola, mum of 14, 13, 11, 9, 6, 4 and 2 year old

    Not only were my kids in awe of what we received from The Mind Expanders Club, but so was I. To be honest, I was actually blown away by the creativity and the obvious huge amount of hours and mind power that has gone into creating such an incredible story and characters for our children to learn from and expand their own creativity and learning.

    Thank you for this. We are so looking forward to next month’s letters and seeing where Professors Marlowe and Whitley are going to be adventuring, and what fun will be inside.

  • Sam, mum of a 6, 4 and 3 year old

    Our family is truly captivated by the recent letters we have been receiving from The Mind Expanders Club. The creative and beautiful writings from characters Professors Ignatius Whitley and Poppy Marlowe has our whole family enjoying the immersive experience of reading these explorers adventures. Not only are the kids completely engaged, but each letter allows for natural exploration of many new and exciting concepts! Such a win when educating kids at home.

    Our kids can’t wait for their next letter, and next adventure.

  • Bridget, mum of 4 and 6 year old

    Our whole family look forward to receiving the Mind Expanders Club in the mail - me, my children and their grandparents too! From opening the envelope, to reading the Professor's stories that are full of fascinating information and beautiful linguistics to the extra interactive activities, we all learn and expand our minds! Highly recommend! We're going to buy our interstate cousins a subscription so they can share the joy and discuss the adventures and learnings together.

  • Bridget, mum of 4 and 6 year old

    We take the Mind Expanders Club ‘Exploring your own Backyard’ Ebook with us everywhere - to our farm, the park and on road trips. As a parent, I appreciate the guidance and insights in the first few pages of the booklet, and my young children are enthralled by the variety of activities that can be repeated on different days and different locations. I love that they can embody Professor Whitley and Professor Marlowe's curiosity, willingness to experiment and appreciate the nature at our doorstep.

Let the Journey begin

The Magic of a Letter in the Post

In a world of buzzing phones and instant messages, there’s something truly wondrous about opening the mailbox and discovering a real letter — one addressed just to you.

A letter you can hold.
Unfold.
Smell the paper, feel the texture, see the stamp.
A letter that travelled through real hands, over lands and skies, to land softly in yours.

At the Mind Expanders Club, we believe mail should be more than bills and flyers.
It should be a spark of curiosity, a portal to another place, a moment to pause and wonder.
When our letters arrive — filled with adventure, discovery, and imagination — you’re not just reading, you’re journeying.
