Not sure why the Telegraph headed it as being about gender.
So I found an English version of their manifesto, and unless these is an additional bit not formally part of the manifesto, doesn't say quite what the article says. The following section is the only one that refers to gender that I could see:
4) Family and generations
The family, as a partnership between a man and a woman with common children, is the natural nucleus that holds a functioning society together, and which, with the solidarity of the generations, underpins our sustainability.
We are committed to equal opportunities between men and women, to mutual respect and to fair incomes, regardless of gender.
We emphatically reject the preferential treatment of a gender to overcome actual or perceived discrimination. Statistical inequalities caused by a variety of factors cannot be evened out by wronging individual people. This is why we speak out against any quota regulation or "gender mainstreaming".
The family, characterised by the responsibility of partners and generations for one another, is the foundation of our society. A child turns a partnership between a man and a woman into a family. Those who take on this responsibility as a single parent form a family with their children.
We are committed to the primacy of marriage between a man and a woman as a distinct way of protecting child welfare. Only partnerships between men and women provide our society with a wealth of children. We reject a separate legal institution for same-sex relations.
As part of the state's role as a protector we acknowledge the need to intervene in the autonomy of the family only where the failure of the family concerned is clearly damaging the welfare of the child.
If parents separate, the emphasis must be placed on maintaining joint responsibility for the child. In the tax system, families are to be construed as an economic community. The pension system must take account of years spent caring for children as well as caring for relatives.
Taking care of children within the security of a family takes precedence for us over substitute state-run systems. Parents should receive benefits to support them with this until school entrance age. At the same time we advocate a broad range of child-care places to offer genuine choice to the benefit of child welfare and professional development.
No leniency should be shown to brute force, especially against children. We are committed to the most severe rules of criminal law for crimes committed against children and vulnerable members of our society.
Austria's future depends on our young people. The purpose of our liberal youth policy is to have enlightened and mature citizens, equipped with all the knowledge and skills they require to hold their own as free and settled individuals.
We are committed to solidarity between the generations and recognise the social, cultural, economic and political contributions as well as the life experience of older generations. We advocate the participation of all generations in decision-making processes and the making of democratic decisions.
We are committed to a harmonised, performance-based and social state pension system as well as corporate and private pension planning.
We are determined to respect the dignity of the elderly and combat all forms of neglect, abuse and violence.

Is there a stand alone statement about this?
