Here in Australia, tomorrow (Sunday 4th September) is Father's Day. A day where we celebrate all the different types of Dads and the roles they play in our lives. Whether they be Dads, StepDads, bonus dads, granddads, honorary Dads, the dads we choose, the dads we know and men who have stepped up into the role without being asked. We also celebrate the mums who pull double duty, who are both mum and dad.

I dedicate this to my amazing mum, who had doubly duty almost my whole life and to whatever you missed, my most beloved Uncle, my mum's brother stepped up, no questions asked and was the best role male role model I could ask for.

I also dedicate this to my own Dad. We've had a tumultuous journey. Either you're in my corner or boxing me into a corner. When you're in my corner, life is great. Unfortunately too many years were spent boxing me into a corner. That's something that's on you. We both know that and you've owned that mistake.

Now you're literally in the fight of your life and I'm by your side, the best you'll let me. I know you don't want me too close and that's OK. But I'm always in your corner.

Keep fighting, the good fight.

F U Cancer!

Final dedication is to my wonderful husband, who is an amazing and loving father to our daughter and to our brightest shining star in the night's sky.

Set in season 20, Tim's missing Gibbs and decides to write to him on Father's Day.

Dear Gibbs,

When I think about today, Father's Day, I think about all the men that have helped shaped me into the man I am and my journey to become who I am.

I think about my late father and his rules. How living under his roof, was never harmonious or even relaxed. I think about how he was more obsessed with trying to rise through the ranks of the navy to become an Admiral faster than what his own father did. Ultimately, I think about how it impacted on the relationship that we shared with one another. Sometimes I felt like I was never good enough for him because I didn't join the navy and follow in his footsteps, in my grandfather's footsteps and in my great grandfather's footsteps. After all, he was fond of saying "Every generation has had some had a McGee in the navy. Until you. You destroyed the McGee naval legacy." See, I'll always be a disappointment to him, even now he is gone. Even after he got sick, I still tried to mend the fences. The distance between us, it just seem to grow further with each year the that passed, no matter what I did.

I think about my grandfather Admiral Nelson McGee next. I think about how he impacted of my life. How he encouraged my love of math and science and took me for who I was, at face value. He taught me the from the difference between morals and ethics. Teaching me the difference from right and wrong, in the process. He was always in my corner even if he didn't agree with my choices. Losing him at the age of 11, broke my heart more than anyone ever realised. Sometimes I wonder what life would be like if I still had him by my side. He taught me the value of a hard day's work and it's something that I strive for everyday in my life. I thank him for that everyday.

There are a few men who touched my life, briefly. Who taught me an important lesson or two.

Jackson Gibbs, who showed me that having a heart of good isn't always a bad thing.

Leon Vance, who has shown me it OK to overcome challenges and diversity the hard way. That life isn't always easy, or fair.

Mike Franks, who taught me the benefits of cantina time, making sure that I always take the time to enjoy life.

Tobias Fornell, who shows the world every day that it's OK if you or someone you love isn't perfect. That true perfection doesn't exist.

Ducky, that no matter where you look, there's a life's lesson somewhere.

Even Tony, that you've gotta always draw the line, somewhere.

Jimmy Palmer, who proves to the world that Dads really are superheroes, they just don't wear a Cape.

Surprisingly, even Parker, who takes his cues with me from you, believe it or not. On the now rare occasion, if I need that push, or I need guidance, he gives it to me. He always tells me to think what would you tell me to do, if you were still here.

Finally, I think about the man who shaped me the most. He moulded me into the man that I am today. That's you, the former Agent Leroy Jethro Gibbs, former marine. A man whom I have always admired and looked up to, no matter the choices he's made. Even if I don't always agree with them and yet, despite that, you're still the best man I know.

It was living and working by your rules, the rules you taught me that has shaped me into who I am; the father I am too. Without meeting you, I wonder who I would have become and where I would be. The influence you've had on my life has been profound. I am stronger, smarter and a better man, for having you in my life. For looking up to you, as my role model.

We didn't always see eye to eye. Especially in the beginning, and I think that was because I grew up in such a militant household. I was taught to respect my elders and call them sir. Boy, did you hate it when I called you sir? You had my respect from day one and that's never changed. More importantly, I've had your respect too.

We had what could be only described as a tumultuous relationship over the years. I was your techy probie and you were my boss. I know I was as green as they came, in the beginning but under your tutelage, I have become the best field agent I could possibly be. You gave me my big break in the field, you could see the potential that I had and you encouraged me to succeed no matter what. I thank you for that.

For 12 years I was your junior field agent and for another 6 years, I was your senior field agent. In those 18 years combined you've had my six and I've had yours, on and off the field. We've literally been together working together side by side in the thick of it, solving cases and bringing closure to victims and their families.

We've been to hell and back, almost literally, from Paraguay to Somalia and to Afghanistan and Iraq. You had my back when I was scared of what the future held after the Conrad Gala. When Dee wanted to go to Dubai, when we wanted to move in together and even when I was worrying about the perfect way to propose. You stood by as I married my wife and you were in my corner when I became a Dad. Even if you're not officially mine.

If I ever set a foot astray in either of those roles as husband or as a father, you set me right side up. You've pushed me when I've need to be pushed and reined me back in when I've need to be pulled back into line.

We spent Christmases, birthdays and Thanksgivings together and somehow we managed to create our own little family. You know, our unique little family. My kids call you Poppy and rightfully so. Not only have you made me a better man, you've been a better person, a better role model, a better friend and a better father than my own father ever was. .

Probably the most important thing you've ever taught me was honour, integrity and loyalty and to never leave a man behind.

I love you, man. Happy Father's Day.

Semper Fi, Gibbs!

Love Tim.
