The level playing field is a myth. For example, height is an obvious asset in the WNBA, where a player like Elizabeth Cambage, who is 6’8,” competes against Lailani Mitchell, who is 5’5.” No one decries that matchup as unfair.

“Going home” is a classic metaphor within the prison system.

But most people exiting prison in Australia either expect to be homeless, or they don't know where they will live.

In my capacity as former prison governor, releasing inmates to homelessness was tantamount to releasing them to failure.

'Bugger this, I'll just go back to prison': Experts say there's one key element to stop ex-prisoners reoffending About a third of offenders enter prison after being homeless. For others, the prospects of finding and affording a rental as an ex-prisoner are slim.

And it would actually save the government a lot of money. It would reduce crime, reduce incarceration rates and more importantly it would save people’s dignity and lives.

Fortune is a cruel mistress – she makes some people poor, and others witless.

Homelessness in Australia needs to be outlawed. Having a home should be a human right for every Australian.

Anyone begging in the streets is clearly not faking poverty or homelessness but suffering from it is actually quite heartbreaking.

To blame the homeless for being homeless is like blaming a pig for stinking.

Is Broken Hill the most progressive place in the country? The local literary and arts communities are flourishing, even as the bars are bursting.

A woman can’t get an abortion in Farrer.
Just like in Wagga Wagga they have to go to Sydney, Melbourne or Canberra.

The Farrer Electorate is my old stomping ground. It's full of Christians,
over 50% of the electorate.

Only 25% voted YES for the Voice which was way below the national vote of 39%.

The same with SSM only 55% compared to 61% for the Nation.

There are plenty of Christian rednecks in Farrer.

My eldest granddaughter is now 19. This is when she was 12. She radiates pride having a trans Nan, and I shine with pride being that outspoken, proud trans Nan. Embracing your true self with unapologetic pride is the ultimate liberation, a feeling no one can ever take away from you.

Trans Women in Sport: What Does the Science Say? Research suggests trans women have minimal to no performance advantage over cisgender women.

And these blanket bans totally ignore the massive diversity among trans women and girls in body size, physiology, training history, athletic abilities etc.

Some sports including @UCI_cycling and @WorldAthletics & @WorldRugby have banned trans women & girls entirely from competing in the female category.

BUT, these bans have NO scientific justification on fairness or safety grounds in a single sport.

A trans woman for example in my sport the @aflwomens a as a prerequisite to even be considered to be approved to compete in female category, the trans woman applicant must, require:

Maintain testosterone levels below a threshold (e.g. < 5 nmol/L) for a set duration (e.g. 24 months).

Effects of gender affirming hormone therapy on exercise performance in transgender athletes The study of the athletic performance of transgender individuals is a novel endeavour. This thesis begins with a systematic review of the changes induced in non-athletic trans women with gender affirming hormone therapy (GAHT) and how these changes may affect athletic performance. The 3 experimental studies in this thesis use different approaches to quantify the changes in transgender athletic performance with GAHT. A longitudinal case study was undertaken to determine the effect of GAHT on the performance of an international level trans woman cyclist (chapter 3). The cyclist demonstrated an ~15% loss of aerobic capacity with 3 months of GAHT and stable aerobic capacity for the following 9 months of GAHT. This cyclist subsequently demonstrated a 19-33% and 15-30% loss of lower and upper body strength respectively with 18 months of GAHT. A retrospective and prospective survey-based study of the performance of trans athletes pre- and 12-86 months post-GAHT in the sports of athletics, powerlifting and swimming was undertaken (chapter 4). In this study, 9 trans women athletes reported that GAHT was associated with female-typical values of testosterone, oestrogen, haemoglobin, and haematocrit. In the same study, 9 transgender women sprinters, middle- and long-distance runners reported a 15% increase in performance times with 5-86 months of GAHT: the increase was 11, 15 and 18% for the sprinters, middle- and long-distance runners respectively. The collective age-grade scores (AGs; male scores pre-GAHT and female scores post-GAHT) of the 9 runners did not change (p=0.304) with GAHT. There was no significant difference between the pre- and post-GAHT training-adjusted AGs for the sprints [95% CI of (-3.0,4.8)], the middle-distance races [95% CI of (-3.7,0.9)], or the long-distance races [95% CI of (-3.1,1.5)]. A single trans man powerlifter reported a linear (r2>0.81, p0.18). The absolute V̇O2peak of the trans women (3.19 L·min-1) was not quite significantly higher (p=0.057) than the absolute V̇O2peak of the cis women (2.83 L·min-1), however the effect size was large (d=0.84). The three studies suggest that athletic transgender women may lose more strength with GAHT than non-athletic transgender women but may still maintain a sizable absolute (but not relative) strength advantage over athletic cis women; that athletic transgender women may have little to no remaining post-GAHT advantage over athletic cisgender women in aerobic capacity; and that athletic trans men may have the capability for substantial strength gains with GAHT. These findings have implications for transgender inclusion policies depending upon the demands of the sport.

A trans woman's body at this stage will be significantly underpowered.

This cyclist had less delivery of oxygen to her working muscles which produces a higher rate of metabolites and consequently results in muscle fatigue.

These drastic performance losses are not surprising. GAHT has marked and consistent effects on hemoglobin and hematocrit concentrations.

Men on ave have 15% greater aerobic capacity than women.

This International level trans woman cyclist experienced a 15% LOSS of aerobic capacity in just 3 months.

Trans women are not delusional; we are fully aware that we were born with XY chromosomes, and we recognise that these cannot be changed. However, we have the ability to alter many secondary sex characteristics and adjust our hormonal profiles, empowering us to live authentic lives.

Sexual Victimization by Women Is More Common Than Previously Known A new study gives a portrait of female perpetrators

Women inmates are more likely to be sexually abused by other inmates than are male inmates.

In juvenile corrections facilities, female staff are also a much more significant threat than male staff.
